What is the first step in the procedures for testing radios?

The first step in the procedures for testing radios is to initiate a voice transmission with another radio. This step is crucial as it allows the operator to establish communication and assess the functionality of the radio equipment in real-world conditions. By transmitting a voice message, the operator can check for clarity, volume, and overall performance. This initial interaction is essential for confirming that the equipment is operational and can effectively communicate with others.

Other procedures, such as performing a visual inspection or logging test results, may follow this initial communication but are not the primary step in testing the functionality of the radios. The emphasis on initiating communication first is a standard practice in radio operation, ensuring that systems are not only functional but also meet the necessary clarity and performance standards before further assessments are made.
